Th is invention relates to carriers for overhead and similar conveyers.and refers par- 1o tieularly to a means for holding the carrier at thepoint where the bucket is to be loaded.

The invention refers, further, to a means for automatically releasingsaid holding means when the bucket is hoisted.

15 The invention further refers to various other improvements in detailhereinafter more fully shown and described.

In the accompanying drawings, Figure 1 is a side elevation of a carrierembodying the 20 features of my invention. Fig. 2 is a longitudinalvertical section taken through the earriage of said carrier. Fig. 3 is asimilar view showing the parts in a different position.

Fig. 4 is a transverse section through the carriage on the line of nohoisting-shaft. Fi

5 is a front elevation of the bodily-sliding latch-bar for holding thehoisting-head to the carriage. Fig. 6 is a. view of the lockinglatch bymeans of which the carriage is retaincd in position during the operationof loading the bucket. Fig. 7 is an end elevation of the hoisting-headand the operatinghead. Fig. 8 is a fragment-.11 sectional view on theline of the pivotal shaft of the bucket.

In the embodiment herein shown and described of this invention I providesupporting-cables 1, suspended in the usual manner across the space overwhich it is desirable to transport material, stretching said cables 40reasonably taut, and. supporting them so that the point at which thebucket takes its lead is somewhat lower than the point to which the loadis to be conveyed.

The hoisting-drum (not shown) is located 5 near the point of deposit, sothat the carrier runs by gravit to its loading position and is elevatedand rawn to its dumping position by the hoisting-drum. The carriercomprises four hanger-arms in pairs 2 and 3, one 50 pair being locatedat each end of a carriage- )odiy com osed of outer plates 4 and intermeiate p ates 5, with spacing-blocks 6 between said plates near the endsof the latter. A guide-wedge 6*, to be hereinafter described, 55 isfixed in position between the plates 5. The upper ends of thehanger-arms are rig- CARRIER.

while their lower ends are secured to the outer sides of the outerplates 4 by bolts passing through the carriage. The upper ends of thehanger-arms 2 and 3 lie near together, and between them sheaves 7 aremounted for running upon the supportingcables 1 and suspending saidcarriage therefrom.

A shaft 8 extends transversely through suitable openings in the plates 4and 5 bearing-bosses 9 being rigidly secured to the outer sides of saidplates 4 to provide suitable bearings for the ends of said shaft.Intermediate its ends and in the spaces between the inner and outerplates I have mounted loosely upon said shaft sheaves 10 and 11, overwhich the hoistingeca-ble 12 is adapted to run. One end of said cable issecuredto the carriage by means of a hook 13, and the other end runningto the hoisting-drum passes from said carriage over the idler-sheave 11,rotatably mounted at the forward end of the carriage.

The outer dates 4 of the carriage-body extend somewhat above the innerplates 5 thereof, a cover-plate 15 being secured in position over theseparating-blocks 6. Between said outer plates at locking-latch 16 isplaced, said latch being pivotally mounted upon a bolt 17, lying insuitable openings in the hangerarms 2. To the upper side of the latch isrigidly secured a bar 18, the ends of which ba extend into concentricopenings 19 in said plates 4,said openings providing a means forlimiting the extent of the pivotal movement of said locking-latch.Adjacent to the latch 16 and in the opposite end of the carriage 12 ayielding bar 20 is mounted, the ends of which bar project outwardlythrou 'h elongated openings 21 in the plates 4. The bar :20 is heldforward toward the center of the carriage by meansof extension coiledsprings 22, secured by suitable means to the outer plates 4 and to theends of said bar. To the upper side of the bar 2U are secured two blocks23.

The hoisting-head 24 is provided with a transverse shaft 25, supportedin bearings in said head, and intermediate its ends has sheaves 26.loosely mounted on said shaft. The sheaves 26 are separated in thehoistinghead 24 byvertieal plates 24' 24 correspondmg in position withthe plates 4 and 5 of the carriage-body, and said sheaves 26 correspondin position with the similar sheaves 10 and 11 and cooperate with saidsheaves to carry the hoisting-cable 12. Upon its oppo site sides thehoisting-head 21 is provided with outwardly-extending cars 27, to whichthe carrying-chains :27 for the bucket-sec-' tions are secured. A dog2's is pivotally mounted within the hoisting-head between theintermediate plates 24* thereof. a bolt :25), passing through suitableopenings in said head, being the means of support for said dog. Theupper end of the dog 23 has a forwardlyexteiiding operating-arm 30,which arm proatch 16.

jects through the open forward end of the hoisting-head 24, between theinner plates 24" thereof. I

The bucket 31 is of the ordinary sectional or clam-shell construction,the sections being pii'otallyconnected bymeans of a shaft 32,- beneathwhich shaft said sections are suspended by means of the arms 33, thelower ends of which arms are rigidly secured to the ends of thesections. The shaft 32 is square in cross-section save for the pointsupon which the arms 3'3 bear upon it.- N ear its middle portion saidshaft carries an unwardly-extending guide and tripping-rod 35, said rod.being pointed at its upper end and adapted to enter the openings betweenthe inner plates 5 of the carriage-body and there engage thelocking-latch 16, which operation will be described more fullyhereinafter.

The bucket-sections are moved into an open position by means of anoperating-head 36, comprising transverse bars 37, through suitableopenings, in which bars a bolt 38 ex tends, which bolt is adapted to beengaged by the dog 28 to hold said operating-head in position relativeto the hoisting-head when the bucket is loaded. At their outer ends thebars 37 carry pivotal links 3!), the opposite ends of which links arepivotally connected with the closing-arms 40, which arms are fixedattheir lower ends to the opposite sections of the bucket- 31. bucket isrovided with a chain 41 at either end, whic i chains connect with thechains 27, depending from the hoisting-head 24, and likewise with chains42, connected to the shaft 32. The hoisting-head also has a rigidupwardly-extending locking-arm 43, the up: per end of which is providedwith a notch 44,]. which notch is adapted to be engaged by the 'ieldingbar 20 in order to support the hoist ing-head from the carriage in theposition shown in Fig. 1. A stop-block 45 is adapted to be secured tothe lower cable 1 by means of clam )ing-bolts 46, passing through thetwo side pl ates 170f said stop-block. The block also has twoupwardly-extending arms 48, between the up-* per ends of which a sheave49 is supported, which said sheave is adapted to rest upon the' uppercable 1. A hook 50 is mounted upon. each side of the stop-block 45, theforward ends of said hooks projecting forwardly a dis tance from saidstop-block. At their rear toward the carriage.

Each section of the" the latter from the stop-block 45. locking-bar 35and the locking and suspendby the guide-wedge 6.

ends the hooks 50 are pivotally mounted ustincnt for the forward end ofsaid hooks.

The books 50 are adapted to enter the upper portion of the carriagebetween the outer panes 4 thereof and there be engz'iged by the Inpractice the cableway is arranged so that the point at which the bucketis to be loaded is somewhatlower than the point to which the load is tobe drawn in order thatthe bucket may be run by gravity to theloading-point. The hoisting-engine for raising and transporting theloaded bucket is lo cated at the discharge end of the cableway. Thestopblock 15 is adjusted in position upon the cables 1 above theloading-point. As the carrier with the open bucket suspended therefromupon the chains 27 approaches said stop-block the locking-hooks 50 arethrust into said carrier beneath the lockinglatch 16. The forward endsof said lockinghooks pass beyond the free end of said locking-latch andengage the blocks 23 upon the "yieldingly-inounted bar 20, pushing saidbar out of the notch -14 of the suspending arm -13 and peru'vitt ing thehoisting-head 24, to which said suspending arm is attached, to drop asthe cable 12 is paid out. hen the open bucket settles upon the materialto be removeth the hoisting-head in turn settles upon the operating-head36, the hook 2S engaging the bolt 38 and locking said heads together.

' The lioistiiigcable 12 is now wound upon the hoisting-drum and thehoisting-liead raised As the hoisting-head approaches the carriage theunlocking-bar 35 is projected upward through said carriage until itdisengages the locking-latch 16 from the hooks 50, and the lockiiig-bar43 in like manner engages the locking-bar 20, locking the hoistingheadto the carriage and freeing The uning bar 43 are guided to their properposition Continued winding up of the cable 12 causes said carriage, with"the loaded bucket, to travel up the incline to the delivery-point,where the hook 128 is withdrawn from the bolt 38 to damp the bucket.
